we rebuilt a blaster last summer with a top end i bought from yes ser. It has been ported and polished with booster ports, fmf fatty, cobra silencer, vitos high compression gaskets, vf2's, vitos jet kit, k&n filter with open air box. He was running a 28mm carb but i have stock on it but if i run anything but stock jets it acts rich? It also gets wet around exhaust flange? With any of the vitos jets it has no bottom end but will haul ass wide open? It has alot of power with stock jets but every once in a while you have to play with throttle to get powerband to come in?
